Group Big Bang put together an unforgettable event for their fellow agency artist Se7en, who is about to go the army.

On March 19, Se7en will be enlisting int he army. With around 10 days left before enlisting, he held his 10 year anniversary concert with his fans.

Se7en expressed his thoughts about going to the army and other YG Entertainment artists attended the event to show their support.

Big Bang also brought out a big cake at the end of the concert to celebrate Se7en's 10 year anniversary.

This may seem normal for fellow artists to bring out a cake for their fellow artists celebration, but the surprise was that Se7en did not think that Big Bang would make it to his concert in the first place.

The situation is as follows:

Big Bang and Se7en are known to be like brothers and have always supported each other throughout the years. 

However, Se7en had received news from Big Bang's manager that they would not be able to make it to his concert because of conflicting schedules.

They did not make a separate video message for him and only sent him a small bouquet of flowers.

Big Bang had already discussed with the staff about their surprise and so Se7en was the only one that did not know that they were actually there.

After his last song, Big Bang came out with the cake and surprised Se7en. Se7en seemed very happy and surprised that they were able to make it to his concert. This showed how tight and close their friendship was.
